It was only my quick fix for the problem, and after applying your fix it
doesn't longer produced a rough 5K difference in size, but my patch still
makes a sound.o which is 1267 bytes smaller. Altough this not much, it can
preserve a kernel page when it's on the 4K boundary.

BTW, Linus has added this way of linking sound.o to linux-1.3.28. :-)
